If there are 12 months in one year, and a decade is 10 years. Then there are 120 months in a decade. (12x10=120)
There are 240 months in two decades, as one decade comprises 120 months.
How many months are in 4 decades
840 months
480 months
120 months in a decade
300 months
1 year = 12 months so 5 decades = 5*10 = 50 years = 50*12 = 600 months!
1.25 decades = 12.5 years12.5 years x 12 months per year = 150 months
1 year = 12 months so 3 decades = 3*10 = 30 years = 30*12 = 360 months!
480. 12 Months a year X 10 Years in a decade = 120 Months 120 Months per decade X 4 Decades= 480 Months
1 year = 12 months so 2.5 decades = 2.5*10 = 25 years = 25*12 = 300 months!
5 decades would be 50 years. Multiply 50 and 12 for months. Your answer would be that there are 600 months in 5 decades.
